Different people get annoyed by different things. While you can often just remove yourself from a situation in public, you don't generally have that luxury at work. So, we want to know: what are your biggest workplace annoyances?

We're all familiar with the classic reply-all gaffe at work, but countless other annoyances exist. Perhaps the person in the desk next to you always listens to death metal at maximum volume on their headphones, or that one guy you've never met always uses the main email thread to post pictures of cats. Whatever your annoyances are—big or small—we want to hear about them (and how you've solved them).
